2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006
Emitter Turn-Off (ETO) Thyristor based STATic synchronous COMpensator (STATCOM) is one of the promising Flexible AC Transmission System (FACTS) technologies, and it is gaining more popularity in utility grids. A 4.5 MVA ETO based STATCOM failed two ETO devices as over-voltage protection triggered AC connector and disconnected the STATCOM from AC grid ...

Overview of STATCOM technologies
2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies. Proceedings, 2004Abstract: /spl plusmn/20Mvar STATCOM indicates that China is the 4/sup th/ country to develop STATCOM in the world. This paper introduces the development of STATCOM particularly in China. Topologies of STATCOM are discussed, and the cascade multilevel configuration is given in details. Power valves such as GTO, IGBT, IGCT, IEGT used in STATCOM are also

PV Solar System Control as STATCOM (PV-STATCOM) for Power Oscillation Damping
IEEE Transactions on Sustainable Energy, 2019This paper presents a novel control of photovoltaic (PV) solar system as a FACTS device STATCOM, termed PV-STATCOM, for power oscillation damping (POD) in transmission systems. In the proposed control, as soon as power oscillations due to a system disturbance are detected, the solar farm discontinues its real power generation function very briefly (few

Quadratic Linearization of STATCOM
2018 IEEE 8th Power India International Conference (PIICON), 2018Control of STATCOM is important for the stability of power system to which it is connected. Since STATCOM dynamics is nonlinear, various control strategies have been proposed including feedback linearization which involves internal dynamics. In this paper, we propose to quadratic linearize the STATCOM equations and the problem of internal dynamics does

Voltage flicker compensation using STATCOM
2009 4th IEEE Conference on Industrial Electronics and Applications, 2009Voltage flicker is considered as one of the most severe power quality problems (especially in loads like electrical arc furnaces) and much attention has been paid to it lately. Due to the latest achievements in the semiconductors industry and consequently the emergence of the compensators based on voltage source converters, FACTS devices have been ...

Dissipativity-based control for STATCOM
PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003This paper describes a dissipativity-based approach for the dynamic control of FACTS devices based on voltage source inverters (VSI), such as STATCOM and UPFC. The main goal of the approach is to achieve the AC current and DC voltage regulation by shaping the energy of the closed-loop system, similarly to Lyapunov techniques.
